TRAVERSE-MOTION FOR YARN-SPINNING APPARATUS.

To all whom it may concern: I

Be it known that I, J0x.as NORTHROP, a citizen either United States, and resident of Hopedale, county of VVo'rcester, State ,of Massachusetts, have invented an Improvement in Traverse-Motions for Yarn-Spinning Apparatus, of which the following descripdrawing, is a specification, like letters on the drawing representing like parts.

This invention has for its object the prolarly adapted for use in connection with yarn spinning apparatus, to impart to the ring-raila peculiar traverse, whereby the yarn islaid upon a yarn-receiver in an improved and efficient manner.

, Several forms of spinning apparatus have been devised heretofore to form upon the arn-receiver or bobbin a preliminary winding or bunch, and thereafter a main or service winding, for subsequent use in' the shuttles of automatic filling-replenishing feeler looms, wherein a feeler operates to effect a change of filling when the yarn has been woven off down to the preliminary winding, which contains sufficient yarn to last while. the change is being made. Suclz spinning apparatus forms the subject matter of United States Patents No. 680194 to Chapman; Nos. 686906, 722,145 and 798704: to Rhoades, and in all of these atents the bunch-like character of the re iminary winding is feature, the bunch eing formed with short and uniform traverses and then the traverse is lengthened automatically for the main winding.

In my present invention I have .de arted very markedly from the structures ant mode 'of operation detailed in the patents referred to, and while the bobbins formed by my novel a paratus are'also designed for use with feelbr looms they possess certain characteristics which result in an improved operation in any loom, Whether supplied with a feeler or not."

It has been found in practice that some-- bin interposes an obstruction to thesfree; delivery of the yarn when the latter, in weaving off, has to draw off over the bunch, the obstruction tending to break the'yarn. By

resent invention I overcome g,

traverse; and while the yarn laid at the very beginning of the operation cooperates at the r0 er timeiivith t e feeler, in a feeler-loom, 1t oes not comprise all the yarn which is laid by a shortertraverse than that employed for the main winding, and therefore it can hardly be termed a bunch in the usual meaning of that word in the art; the yarn mass remaining when the feeler acts has less length, relatively to its thickness, than heretofore, and consequently there is a less quantity of waste even should the setting of the feeler' be imperfect.

The weaving ofi' of the yarn from a bobbin produced in accordance with my resent nvention is'not obstructed in the s ightest froln the beginning to the end of the weaving off, and while there is a small portion of the yarn adapted to effect the proper operation of a feeler it offers no. obstruction to the yarn as it is drawn ofi" the bobbin. .1 am also enabled by my invention ;to spin a greater quantitv of yarn onagiven bobbin, as will ap ear hereinafter. 1

he mechanism hereinafter to be de scribed, as illustrating one practical embodiment of my invention, is" very simple and composed of few partsfand it is readily applicable to the ordinary ring-spinning apparatus with slight expenditure of time and labor. -The operation of. the e'chanism is entirely automatic fro'mista'rt ,to-finish' in winding the yarn upon a bobbin.

1 The various novel features of my invention will be fully described in the subjoine'd specification and particularly pointed out in the following claims. g Figure- 1- is a front elevation of a portion of .a spinning-frame-having-one embodiment of my present invent-ion applied thereto, the parts being shown in readiness to begin the winding of a s et:of bobbins, the ring-rail being at its lowest point; Fig. 2 isia transverse sectional view onthe line 2-2, Fig. 1, looking toward the left, the actuating cam for the builder-motion being partly. broken out, and the builder-arinbeing-at the bottom of its {,stmhe; Fig. 3 is a detail in front elevation of Fig. 4 is a view similar to --5 "the position assumed byw-thrnembers when the maximum traverse is attained Fig. 5 is a top plan view of the parts shown in Figs. 3 and 41-,and also showing the controlling device whereby the traverse of the ring-rail is gradually increased from minimum to maximum; Fig. v6 is a vertical sectional detail on the line 66, Fig. 5, to show more clearly a portion of the controlling device, to be referred to; Fig. 7 is a rear view-of the segmental, angularly movable carrier and the guide thereon, illustrated in front elevation, Figs. 1, 3 and 4; Fig. 8 is a detail view of the drum shown by dotted lines in Fig. 1; Fig. 9 is a view in elevation of a bobbin with a small portion of yarn wound thereupon, shortly after the beginning of the winding operation; Fig. 10 is a similar view, broken out between top and bottom, of a full bobbin, showing the general shape thereof and the increased quantity of yarn upon the lower end Fig. 1 1 is a sectional view of one half the yarn mass to better illustrate the manner in which the yarn is laid upon the yarn-receiver or bobbin.

In the present embodiment of my invention the ring-rail is raised by a suitable lift-' ing-we'ight and depressed by or through means actuated by the builderwmotion, the usual winding mechanism thereof letting oh the cl: ain from the barrel gradually to e'li'ect the gain of the traverse, as the yarn is laid upon the yarn receiver. Ordinarily the gradual unwinding of the chain attached at one to the barrel will cause the ring-rail to rise a little higher on each ascent, and at each descent to go not quite so low as on the previous descent, to lay the yarn in successive layers'upon the bobbin from the base to the upper end thereof. Herein, however,'1 have modified the action of the winding mechanism, as to the gain of the traverse at both its upper and its lower end, as will be explained, whereby nirnarily the yarn. is laid with. a gradually increasing traverse, and the lower end or base of the yarn mass is conveXed or rounded, instead of upwardly at ered, thereby increasing the amount of yarn aid.

In Figs. 1 and 2 the spindle rail 1, rotatable spindles 2, the vertically reciprocating ring-rail 3 provided with rings 4 for the'spin- .dles, the littenrods 5, only one being shown in Fig. 1, the rocker 6 cooperating with the foot of the lifter-rod and providedwith a weight 7 to elevate the ringrail, and-'tn'e up turned rocker-arm 8 rigidly connectedwlth' the rocker and transmlttmg reciprocating movement to the other lifter-rods through' link 9, may be and are all substantially of well known or usual construction in spinning or similar apparatus; has the usual segment 10, Fig. 1, and herein I h: vs shown a branchll adjnstably connected with the-rocker-arm, the branch having portion embracing the arm and longitudinallyslptted at 12 for a clamping bolt 13,

The rocker arm 8 whereby the branch may be adjusted longitudinally of the arm, to vary the swing of the rocker-arm, as is usual.

The builder-motion herein shown includes a builder arm 14: fulcrumed on the main frame at 15, Fig. 2, and provided with a to cooperate with a single actuator, shown as a traverse-cam 17 having four polnts, the weight 18 connected with the builder-arm mounted on the arm and acting tokeep the follower 16 in engagement with the traverse cam. stroke, aswill be manifest, and upon the arm is mounted substantially usual winding rel 19, pick-shaft 20 provided with a worm 21 to effect gradual rotation of the barrel, pick-wheel 22 on the shaft 20, an actuatingpawl 23 operated in usual manner, and'a chain 24 wound around and attached to the barrel, the chain l ing in one of the grooves of said barrel. The chain 24 is carried upward and secured to a rotatable drum supported in arms 25, 26, of a bracket or stand 27 bolted to one end of the main frame, above the builderqnotion', as shown in Fig. 1, the bracket arms having extended through thema fulcrum rod 27 on which the drum 28 is mounted to rotate, the said drum having a peripheral groove 29 formed bythe end and center flanges 30, 31, and a disk 32 of considerably greater diameter than the drum is secured to or forms a part of it, the disk and the central flange 31 forming a second peripheral groove. tom of the groove 29 is cylindrical and the chain 24, which is attached to the drum within said groove gradually winds onto the drum, asit is let olf, little by little, by the winding mechanism, in usual manner. The groove between the center flange and the disk 32, however, is in the present embodiment of my invention non-cylindrical, the bottom of the groove being slabbed off or flattened as at 33 clearly shown in ,Fig. 8, for a purpose to be hereinafter described. The disk 32 has extended from its front face a pin or stud 34 near its'periphery, and between the disk and the bracket arm 26 is mounted a segmental carrier 35'having proan elongated lug or ear 36, and fthe carrier ""is also provided with a roller or other stud 37, the guide and stud being very clearly shown in Fig. 7. The carrierhas a hub or ;to swing about said rod and to move the guide 36 in a. curved path above'the drum ,,and through an are having a much greater radius than the radius of the drum. The controlling means whereby the angular roller or other stud 16 constituting a follower.

Said builder 'arm has a constant mechanism, including a double-grooved ban,

The botjecting from its inner face a guide shown as movement of the carrienand its guide is gov counterbalancing the weight of the parts ...sheave 38 through which the fulcrum-rod 2] X extends, the carrierbeing thereby fulcrumed tend up to the outer face Of'tllG disk 32, as

best shown in Fig. 2.

A chain or other-flexible member 39 is pivotally connected at one end to the stud 34, and is thence 'carried under the hub- 38 and upwards over the roller or other stud 37 and the guide 36, and thence toward the branch or arm 11 attached to the rocker arm 8, a connection between the flexible member 39 and said arm 1 1 being effected in the present embodiment of my invention by a longitudinally adjustable link 40, the two members composing the link being connected by a turn-buckle or other suitable adjustable coupling 41, see Fig. 1. By lengtheningor shortening the link, it will be manifest that the distance between the u per end of the arm 11 and the nearer en of the flexible member 39 can be increased or decreased for a purpose to be hereinafter referred to. The

upper surface of the guide 36 is convexed, as

shown, and the member 39 rests upon such convex surface.

ing to Viewing Fig. 1, it will be seen that if the disk 32 is turned in the direction of the arrow 33, said member or chain 39 will be unwound more or less from around the hub 38, accordthe extent of such angular movement of the disk, the chain of course slackening during such movement, but to a' very slight v degree. The link 40, flexible member or chain 39, and the disk 32, form a connection 35 between the ring-rail and the builder-motion. When the builder-arm 14 rises, the wei ht 7 will act to swing the rocker-arm 8 to t e right, Fig. 1, to elevate the ring-rail,

and through the connection just described,

the drumand disk will be turned more or less in the direction of the arrow 33, depending of course upon the amplitude of the stroke of the builder-arm. When the builder-arm descends, the drum and disk-will be rotated in a reverse direction to the arrow 33, and the chain 39 and link 40' will be tightened again, but owing to the gain due to the Winding mechanism, said disk will not return the stud 34 to exactly the point shown in Fig. 1, but such point will be advanced, though to a very slight degree, and as the operation continues,. these slight advances will finally make a considerable change in the position. of the parts when com ared the flattened portion 33 of the drum herein'' before referred to, said chain and the drum forming a second connection between the builder-motion and the ring-rail, it being understood of course that the chain 24 is the as shown in Fig. 1.

connecting member between the drum and the buildermotion-. For agiven angular movement of the disk and driim from the position shown in Fig. 1, due to oscillation of the builder-arm, it will'be manifest that the member or chain 42 will give ed a greater amount than the member or chain 39 because of the difference in radii of the sheave or hub 38 and the drum, and consequently when the yarn winding operation begins, the chain 42 will slacken slightly, as the ring-rail rises, so that the up er end of the stroke of the ring-rail is contro led by or through the chain 39, and on the descent of the ring-rail the lower end of its stroke will be determined by the chain 42, as the latter tightens more quickly than the connection including the member 39, it being remembered that on the down-stroke of the ringrail the disk and drum turn in the direction opposite to the arrow 33, and'on the upstroke they turn in the direction of. said arrow.

The'bracket 27 is provided on its top with bridges 43, .44,- to retain in place and also to guide a cam-like controller 45, shown in plan in Fi 5,"as substantially triangularin shape, t e rearward inclined edge 46 cooperating with a follower shown as an arm 47'longitudinally slotted at 48, see Fig. 7, to receive the controller and extended forward and pivotally connected at 49 with the carrier 35', the outer end of the slot 48 being beveled as at 50 to engage the diagonal or inclined edge 46 of'the controlling member 45. If the latteris held stationary, it will be manifest that the carrier can have no movement on its fulcrum 27 and conse- %\i iently the guide 36 will be stationary.

hen, however, the controllin member 45 is moved in the direction of the arrow 51,

see Fig. 5, the follower 47 will be permitted to move to the right, viewing Figs. 1 and 5, and thereby the carrier 35 will gradually move the guide 36 and stud 37 from the position shown in Figs. Land 3 to that shown in member 45 is-efi'ected intermittingly and is controlled by or through the builder-motion. Referring to Fi 2, the straight extension 52 of the" contro ling member 45 is con- 'nected,by a link 53 with the upper end of an arm 54'-mounted on a fixed fulcrum 55, the end of .the arm below the fulcri'iinbeing slotted longitudinally as at 56. ,An extensi'on 57 is adjustably secured to the lower end of the arm by a clamping bolt 58 extended through the slot 56, the extension.

having connected with it one end'of a link 59', the other end of the link having attached to it a'short chain 60 which is wound around this barrel 19 of the winding mechan- The movement of the controlling ism in theisecond one of the grooves thereof,

, 7 As the winding Inechan chain 24 little by little, it also lets oi? the chain 60, and consequently the controlling member 45 is moved, to the left,

vi'ewin Fig. 2, owing to' the pullexerted on mechanism operates, the gain due to the unwinding of the chain 24 from the barrel vis given to the flexible member 39. on the 19 will cause the ring-rail to descend, not quite so low as it did on the previous stroke, and as the stud 34. is gradually advanced by or through the action of the winding mech anism of the builder-motion the ring rail will rise a littlehigher on each rip-stroke. It is desired, however, to wind a portion of the bobbin with a traverse gradually i;-

creasing' froin the minimum traverse to the maximum, and this increase of the traverse is e'iiected by the gradual and intermittent movement ofthe guide 36 to the right Fig. 1,

as the cam-like controlling member is gradually moved in the direction. of the arrow Remembering 51, Figs. 2 and 5.. This controlling device.

ls-governed by the builder-motion, as has been described, and it causes the ring-rail to ascend a greater distance on each rip-stroke than the gain at the lower end of each stroke, the latter being due to the action of the builder-motion and winding mechanism thereof conveyed through the chain 42. Hence the traverse gradually increases until, owing to the gradual advance of the seg mental carrier 35 and the disk 32, more slack up-stroke of the builder-arm than is given to the chain or connection 42, and at this point in the operation the position of the parts is shown in Fig. 4, when the maximum traverse has been attained. The advance movement of the segmental carrier 35- continues thereafter until the edge v of the follower 47 moves of! the diagonal face'46 of the controlling member, maintaining the connection 39 slack While the connection 42 operates. hen the maximum traverse is attained the chain or connection 42 then assumes entire control of the ring-rail and governs the rise of thelatter as Well as the descent on each stroke, andthe traverse Will' consequently be uniform, as the Winding mechanism provides for a uniform gain.

If the surface of the drum 28 around Which the flexible member 42 passes were completely cylindrical, the gain at the bottom of eaclrtrav erse would be uniform from. the beglnnmg to the end. ofthe operatlonofwvindr lng the yarn upon a yarnrece1ver or bobbin,

'but the flattening of a portion of the pe riphery of the drum, as at 33 causes a variation in such gain. So long as the member 42 draws across the flattened portion 33 the start is very minute, but it Will be slowly and .gradually increased as the drum advances and hence the mass of yarn at the base of the bobbin will be built out or rounded as at 61', Figs. 9, 10 and 11, up to the po nt Where the yarn is laid with a second or uniiorm traverse. By this time the drum has advanced to the position shown in Fig. 4, so that from that point to the end of the operation, the member 42 draws ofi' from a cylindrical part of the drum, and hence the gainis at its maximunrand due entirely to -the' builder-motion and is uniform for each traverse. The amount of yarn added to the yarn mass on the bobbin by this arrangement is shown in Fig. lO,.as Without it the lower portion of the bobbin would be shaped as indicated the'divergent dotted lines 62.

In Fig. 11, I have endeavored to indicate the successive layers or windings of yarn, first with a gradually increasing traverse up to-a maximum, and thereafter with the maxi mum traverse, and it will be seen by refer ence to that figure, and also to Fig. 9, that while there is an initial Win ding as 63 on the bobbin, it does' not partake of the characterof the running filling. As a matter of fact with a bobbin wound by the mechanism embodylng my'present invention, there'is conthe time the feeler acts, relatively to the bunches heretofore Wound, and consequently a less amount of yarn left on the bobbin should the feeler be actly.

- In order that. the upper portion of-the primary Winding of yarn upon thebobbin set improperly or inexnecessary to make a change in=the speed of the ring-rail at the upper part of each traverse While the Winding is proceeding With a gradually increasing traverse. That is, by

In order to adjust the length of the minin'.um traverse, .the link 40 is lengthened or shortened, in order to thereby permit the niember42 to be in its work a little sooner 0:? a little later. 5y lengthening the link 40, the length of the -1ninimum traverse will be increased, and itwill be decreased by shortening the link, but it will be understood that these changes in the length of the minimum traverse are co]nparativeb very slight. The more rapidly'the carrier 35 is moved from starting position, Fig. 1:, to final position Fig. 4, the quicker will be completed the winding of yarn with the gradually increasing traverso, and the adjustment of the part 57 on the lower end of ,the arm 54 provides for such variation. If the said extension 57 is moved downward from the position shown in Fig; 2, the distance from the fulcrum 55 to the link 59 will be increased, and therefore the movement of the cam, or controlling member 45 will be slower, whereas if the extension 57 is moved upward to' bring the link 59 nearer ling member 45 will be hastened and conse quently the windin creasing traverse'wil be shortened.

the ring-mil, as when the- The oscillation of the builder-arm'has no articular effect on the arm 54, asthe point of connection between the link 59 and said arm is so near that of the fulcrum 15 on which the builder-farm oscillates.

The novel mechanism herein set forth is very simple in its structure, and is very readily applied to a. spinning frame of usual construction, for .it will be seen that the bracket 27 carries everything requisite to form the bobbin','- first with it gradually increasing traverse, and thereafter with a uniform 'or constant traverse, with the exception of the arm 54.

; ;When the member 42 has sole control of yarn is be ing laid with a constant traverse, the continued advimce of the segmentalcarrier 35 and the" 'upon the ring-rail.

with a gradually in- 'nection including means disk 32 slackens or cases off the flexible member or chain 39, keeping pace with or exceedlng the gain due to the Winding mechanism transmitted through the member 42, for as soon as said member 42 assumes complete control of the ringrail, the other connection between the ring-rail and the builder-motion becomes inoperative to exert any control A lug 35 011 the outer face of-the segmental carrier 35 is adapted to bear against the bracketarm 26-when the carrier is in its extreme advancedposition, to at such time relieve the strai ht extension 52 of the controlling member 45 from any further strain due to the ull through the chain and link 39 and 40. Xfter the full arn load has been laid u on a set .of bob ins and the frame is do ed, the winding mechanism is wound down in usual manner, and thereby the two connections between the ring-rail and the builder-motion are restored to the position shown in Fig. 1 in readiness for the winding of a fresh set of bobbins.

During the formation of the primary winding of yarn, the builder-motion acts upon the ring-rail first through one connection and then through the other, in alternation, to

, control the upper and lower ends of the traverse respectlvely, as has been described, and when the maximum traverse has been attained, one of the connections becomes inoperative automatically, and the other connection completes the secondary winding with a constant traverse.-

My invention is not restricted to the pre. cise construction and arrangement herein shown and described, as the same may be modified or rearran ed in various particulars by those skilled in t e art without departing from the spirit and scope of my invention.
